  These are special anti-virus disks that can be used to scan the computer without starting the OS.

Why use Rescue Disks

1. Rescue Disks can scan when the operating system in not ON, meaning if a virus is preventing it's deletion under Windows or any other operating system, the anti-virus on the rescue disk will instantly be able to remove the infection as the operating system is not active, rendering the virus inoperative.

2. Rescue Disks can help when Windows refuses to start due to virus attack. Just pop in the disk and let the scan begin, hopefully it can fix the problem by removing the virus.

3. Rescue disks aren't prone to virus attacks themselves as these are CD's normally (which are read only), or even if one uses USB devices, the virus cannot operate as it needs the operating system to work. Note in case of USB device, your BIOS has to have the ability to boot from USB device.

4. You'll definitely need a Rescue Disk if the over-smart virus doesn't let an already installed anti-virus do its job.

5. You'll definitely need a Rescue Disk if the virus prevents any attempts to install a fresh anti-virus.

Though one does not need something as severe as a Rescue Disk nowadays, I still prefer this method to booting into the OS and then scanning, as it's a lot more thorough.

Free VS Paid

This debate can go on for eternity - What is better paid or free? Let's not get into that, though I can say that free Anti-viruses generally do not allow one to create a "Rescue Disk", this option often is left to paid counterparts. However, there are always nice blokes that allow one to download/make Rescue disks for free, mind you these aren't worse or cut down versions of paid counterparts. Though I would still recommend you to check documentation before using an Anti-virus that claims to be free, as some scan and recognize for free but do not remove viruses.
